The IRS100-3-25Z15TS3 robot is mainly used for processing, manufacturing, and assembling in narrow spaces. As a robot in the 3 kg class, this robot features high cyclic movement speed and repeatability. Thanks to its short arm (250 mm), this robot boasts high response speed in its peers. Moreover, its internal structure and arm housing are optimized to improve the arm stability and anti-interference ability for internal components. This allows flexible and fast movement and internal protection for the robot in the smallest spaces.
